I've been meaning to learn bass for a while now. I've been playing bass at peoples' houses and at music stores, playing basic basslines and stuff. I just need help deciding what bass to get. First of all, I am definitely getting an SX. It's an issue of what SX to get. I'm really looking for something that will be good for progressive rock, such as Rush, Yes, and King Crimson and metal, such as Iron Maiden, Black Sabbath, and Metallica. It also should be really versatile, meaning good for slapping, fingerstyle, and pickstyle, mainly with a felt pick. I've heard a jazz bass is really good for this, but I just want to be 100% sure. Also, what body and neck should I go with? I'm most likely going to get an alder body, because it's standard. Should the neck be rosewood? I figured rosewood would be good because it would balance out the mids on the jazz bass, so it wouldn't be too high, as opposed to a maple neck, which would have a really bright tone. String-wise, should I keep the D'Addarios it came with? And is it worth adding a Badass II bridge? And what about straplocks? And I don't know anything about amps, so what do you recommend I get?
